jensen air antenna quality
I am getting poor reception from my Jensen air antenna in my 2011 B+. A neighbor in my campsite, about 300 feet away with the same antenna, is also hot happy with the Jensen, but they do get about 5 c...

All Television antennas are a compromise.. You decide what you want and someone makes one that delivers.
There are a couple of Flying Saucer designs these are usually (There is an exception) Omni directional antennas,
Advantage: No need to aim,, Disadvantage, Short range and subject to multi-path intererence causing them to not be very effective.
Wide beam antennas like the JACK. (They also make an Omni) rotatable.
Slightly longer range on axis (in the direction they are pointing, or in the case of the jack, opposite the direction the antenna appears to point)
Some multi-path rejection,, Better performance
Disadvantage: need to aim
Tight beam (Winegard Sensar IV)
Advantages: Better range still, better long range performance, Narrower beam width means you are more likely to need to re-aim for different stations.
VERY HIGH GAIN ANTENNAS.. Like Channel master's biggest offering.
Advantage: Much longer range, much better performance
Disadvantage: Not compatible with RV life style as folding these up for transport (And setting them up again on site) is like a 30 minute to an hours' work and you need a mast and rotor to handle them. Recommended for folks who park it for long periods where the Winegard don't cut it. I have seen VHF LOW stations over 100 miles away with one of these (on top of a 100 foot tower).
Improement: Antennas that use 12 volt to the head can benefit by replacing the indoor module (power supply/switch) with a Winegard Sensar Pro multi-function device. If you have a matrix switch (Box of many buttons) as I do put the Sensar Pro between it and the antenna.
Normally I do not recommend ANYTHING in that position, but the Sensar Pro is the exception.
